Abstract:
We study controlled differential equations with unbounded drift terms, where the driving paths is ν - Hölder continuous for ν (1 3,1 2), so that the rough integral are interpreted in the Gubinelli sense for controlled rough paths. Similar to the rough differential equations in the sense of Lyons or of Friz-Victoir, we prove the existence and uniqueness theorem for the solution in the sense of Gubinelli, the continuity on the initial value, and the solution norm estimates.
